To all whom it may concern Be it known that I, COMTE Yvns on LA Poiizn, a citizen of the French Republic, re-

- siding at St.-Fu1gent, Vende, France, have lid invented certain new and useful Improvements in Radiators, of which the following is a specification.

It has been already suggested to build radiators for central heating by arranging side by side a certain number of vertical chambers in which the heating agent circulates. The said chambersare connected together at their upper and lower ends by means of parallel distributing pipes which are connected to the general circuit of the in.- stallation. In order to increase the efliciency of such apparatus, and to produce automatically a circulation of air through the heating element, there have been arranged, on the lateral walls of the said chambers, inclined conducting ribs, formed on the said walls as inclined ribs which, while acting as radiating ribs, offered the further advantage of receiving the heating fluid, and consequently of increasing the exchange of heat. Again, in order to increase the efliciency of such apparatus, it has been proposed to act on the circulation of the heating fluid in the chambers themselves. To that end, the said chambers, whether combined with inclined conducting ribs, or not, are constituted respectively by series of superposed quadrang-ular chambers which communicate with each other at their corresponding aplces, so

as to force the current of fluid to undergo a.

series of contractions and expansions improving the exchange of heat.

In any installations of the kind described, it is found however that there are numerous eddies in the circulation of air through the heating elements. As these eddies result in a loss of head and unfavorably affect the contact of the fluid to be heated, with the radiating walls, one would think that it would be still further possible to increase the efficiency of the radiators described, by improving the circulation of air between the vertical walls of the chambers and the oblique partitions cooperating with the latter. In order to do this, it must be borne in mind that the two main causes interfering with normal circulation of air and producing eddies, are the disturbances caused, firstly, in the flow of each fluid current between two parallel o'blique walls belonging to adjoining chambers, and secondly, in the circulation of Specification of Letters Patent.

the various currents, externally of the radiating body. In fact, as the air progresses between the parallel walls of the chambers, in order to .pass from the lowest inlet section comprised between two inclined partiti0ns,to the oppositedischarge section, there takes place an increase of its volume, owing to the expansion produced by the increase of its temperature. But as the inclined partitions are parallel, the fluid, on its way to the outlet openings, is exposed to a counter-pressure which retards its escape and which, by causing an expansion, produces eddies outside the apparatus. On the other hand, as the inclined partitions are limited to one and the same vertical plane, it will be understood that each current of hot air escaping from each of the conduits formed between the pairs of inclined partitions, is interfered with, and interferes with the circulation of other currents, as all the latter have the tendency to rise vertically by sliding along the rear partition of the radiator. lhere is therefore still a production of eddies interfering with the normal automatic circulation of air in the room to be heated, and through the radiating elements.

This invention relates to a method by which the disadvantages are removed by rendering more regular the circulation of air in the radiators which are constituted by vertical chambers, in the lateral walls of which are provided inclined ribs forming guide partitions. This method mainly consists in each chamber being made in the shape of a triangle, instead of a quadrangle, v

sponding to' the inclined side of each trian gular chamber, so that the said-outlet orifices are moved horizontally relatively to each other, soasto enablethe, fluid currents which Patented Apr. U, 1917..

escape and rise vertically, to follow parallel paths.

In the accompanying drawing a construction according to this invention is illustrated Figure 1 showing in front elevation several elements, one of which is in section. 1

gig. 2 is a corresponding side elevation, an Fig. 3 showsthe whole in perspective.

The radiator is constituted by fitting together several interchangeable elements, the

trlangle, are provided respectively with a collar 6 and 0 establishing communication, between each chamber and that of the adjoining element. Oblique'ribs d, with varying inclination relatively vto the horizontal, are stamped out in the lateral walls of the said chambers,- and form, in addition to inner expansion chambers, contact surfaces between two elements, so that they form between them passages e widening upward. It

will be seen-that the cross-section of the passages in question, owing to the divergence of the ribs, gradually increases from the cold air inlet to the hot air outlet, so that the fluid can freely expand without being exposed to counter-pressure producing'losses of head or eddies.

Moreover as the discharge orifices terminate at the longest side of the vertical chambers, it will be seen that in the horizontal projection they are shifted relatively to each other. The fluid currents escaping out of the corresponding passages e in order to rise afterward vertically, do not therefore interfere with each other,smce, owing to the re- I spective positionsof the orifices enabling them to escape, they can circulate parallel to each other. A sheet metal plate f forming a 4 screen, could be arranged at the back of the radiator, in order to guidethe whole of the said currents and prevent their coming out and also to give the radiator the appearance The upper portion for the hot air, is grating or perforated parbeing of triangular shape the smallest side of which serves as a base for the radiator, ribs of different inclination being provided on the exterior of the said walls, which ribs form between them air circulation conduits inclined on two opposite walls gradually widening in the direction of the outlet for the hot air so as to present superposed outlet orifices.
